Miyagi Turbo ??
Early on in the film Daniels meets up with Allie and her friend at school. When Daniel explains his head injury as a "bike accident", Allie's friend asks Daniel what kind of bike he has. She assumes he has a motor bike or motorcycle.
Daniel's response is "no, it's kind of a Miyagi turbo actually..."
Then Allie laughs at his answer. As if she knew it was a joke.
He pronounces this the same way he pronounces Mr. Miyagi's name early on.
This never made sense to me because at this point in that movie he only had met Mr. Miyagi twice briefly but never even knew his name yet.
I always thought it was a continuity error. Maybe that scene was supposed to come after Daniel officially meets Miyagi and learns his name
